TH RUST-BEARING.

SPECIFICATION forming part of Letters Patent No. 612,398, dated October18, 1898.

Application filed July 29, 1898- Serial No. 687,173. (No model.)

1'0 alt whom it may concern:

Be it known that I, EDWIN CAEvER,a citi' zen of the United States,residing at Florence, in the county of Switzerland and State of.Indiana, have invented certain new and useful Improvements 1n'lnrust-liearlngs; and 1 do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and usethesame.

My invention has relation to improvements in thrust-bearings and meansfor lubricating the same; and the object is to provide a bearing for theend of a shaft which will resist the thrust of the shaft and at the sametime will supply the requisite lubricant thereto, as hereinafter will bemorevfully described and the novelty thereof be particularly pointed outin the claims.

I have fully and clearly illustrated the invention in the accompanyingdrawings ,where- Figure l is a longitudinal vertical section through thebearing-box, showing the shaft arranged therein and my improved thrustbearing applied. Fig. 2 is a transverse section through the bearing-boxon line :20 a: of Fig. 1, showing the thrust-bearing in face view, thecourse of the lubricating-duct being indicated in dotted lines. Fig. 3is a vertical section of the thrust-bearing, showing thelubricating-duct therein.

Referring to the drawings, A designates a strong two-part metalbox-bearing formed with a journal-seat 1, adapted to receive and holdthe end portion of a shaft, and having a strong upwardly-projecting endpiece 2 to resist the pressure of the thrust to which the shaft may besubjected, and through the end piece 2, centrally therein, is let astrong adjusting-screw 3, provided with a handpiece 4, by which'thescrew may be turned and adj usted. On the lower section or part of thebearing-box is fitted a strong cap 5, the inner end of which fitsagainst the end piece 2 of the lower section and is formed with acentral open-end slot or recess 6, in which fits the neck or projectionon the thrustbearing.

The cap 5 of the bearing-box is secured in place to the lower part bymeans of any proper fastenings, as by the usual bolts, as shown.

B designates my improved thrust-bearing composed of a substantial diskof suitable metal formed with a vertically-projecting neck-piece 7,adapted to set within the recess or slot 6 in the cap of the bearing-boxto hold the disk against movement and position by the action of theshaft. In the thrustbearing B is formed a lubricating-duct 8, leadingthrough the neck-piece 7 and opening at the center of the disk,.as shownin Fig.

3 of the drawings, and suitably mounted on the neck-piece 7 inconnection with the lubricating-duct 8 may be an oil-cup 9, by which thelubricant is supplied in a well-known manner.

It will readily be perceived that my improved thrust-bearing isapplicable to horizontally-disposed shafts having an end thrust, andalso to vertically-arranged shafts, in the latter instance thelubricating-cup being arranged in vertical position to convey thelubricant to the shaft.

My invention is particularly applicable to the shafts in verticalcorn-mills, crushers, &c., wherein the shafts have an end-thrustpressure.

Having thus described'my inventiomwhat I claim, and desire to secure byLetters Patent, is-

1. A thrust-bearing for shafts comprising a bearing-box composed of twoseparable sections, the lower part or half being formed with a verticalend piece to resist the thrust of a shaft and the cap of the box beingformed with an open-end slot or recess, and a thrustbearing disk in theend of the box, formed with a neck-piece adapted to fit in the recess ofthe cap to prevent the disk from turning, and an oil-duct leadingthrough the said neckpiece into the disk and opening centrally therefromsubstantially as specified.

2. A thrust-bearing for shafts comprising a bearing-box comprised of twoseparable sections or parts, the lower part or half formed with avertical end piece to resist the thrust of a shaft, and the cap of thebox formed with bearing-box to adjust the thrust-bearing, suban open-endslot or recess, a thrust-bearing stantially as described. 10 disk in theend of the box formed with a neck- In testimony whereof I affix mysignature piece to set in the recess of the cap to prevent in presenceof two Witnesses.
